Gas light lamp post



United States Patent O 3,161,357 GAS HGHI LAM? PQ-SI Thomas Hart, did W.th St. S, Newton, Iowa File; lidar. i4, i963, Ser. No., Zaldil Claims.(Cl. 24d-S2) This invention relates to gas light lamp posts andparticularly to the unit connecting the standard to the lantern.

Heretofore, there has been a problem of not being able to positionsuiiicient gas feeder tubing in the coupling unit between the standardand the lantern to permit their separation. The coupling unit had to bedesigned small to avoid destroying the ornamental composition of thelamp post.

Therefore, it is an object of this invention to provide a gas light lamppost wherein the lantern may easily be removed from the standard.

It is a further object of this invention to provide a gas light lamppost having a coupling unit between the standard and the lantern thatwill permit storing of a length of gas feeder tubing that may beextended beyond the normal length of the coupling unit when the lanternis removed frorn the standard.

It is a further object of this invention to provide a gas light lamppost wherein the gas feeder tubing is coiled within the unit couplingthe standard to the lantern and may be extended beyond the length of thecoupling unit when the lantern is removed from the standard.

it is a further object of this invention to provide a gas light lamppost having a unit coupling the standard to the lantern which isparticularly suitable for use with a standard comprising a plurality ofsolid legs.

t is a further object of this invention to provide a storage unit for alength of tubing whereby the tubing may be extended beyond the length ofthe storage unit.

It is still a further object of this invention to provide a gas lightlamp post economical to manufacture, durable in use and refined inappearance.

These objects, and other features and advantages of this invention willbecome readily apparent upon reference to the following description whentaken in conjunction with the accompanying drawings, wherein:

FIG. l is a side elevation view of the assembled gas light lamp post;

FIG. 2 is a cross-sectional view taken along line 2-2 in FIG. 1 of theunit used in coupling the standard to the lantern and showing the gasfeeder tubing coiled and compressed in the limited space in the couplingunit; and

FIG. 3 lis a cross-sectional View of the coupling unit of FIG. 2disassembled and showing the gas feeder tubing coiled and extended.

The gas light post of this invention comprises generally as shown inFIG. l, a standard I il and a lantern l2 coupled by a unit i4.

The standard l@ comprises three solid leg members 16 uniformly spacedaround a pipe member 18. Extending the length of the pipe member l is agas feeder tube 2i) (FIGS. 2 and 3). The lower ends of the leg members16 and the pipe member 1S may be planted in the ground to any desireddepth, usually not lower than the transverse brace elements 22 extendingadjacent the ground between the pipe member I3 and each of the legmembers 16.

In order to maintain the symmetry and composition of the standard 1lireflected in the leg structure 16, the pipe l used should have adiameter no larger than reasonably necessary to accommodate the tubing2i). The upper end of the pipe member 18 (FIGS. 2 and 3) is secured tothe unit i4 in any suitable manner.

Referring now to FIG. 2, it is seen that the unit ld compnises a pair oftelescoping cylindrical sections 24 and 26 which are secured againstrelative movement by a pair of screws 27 provided in their mating wallson opposite side thereof. The shorter section 24 of the two is securedto the bottom side of the fiat lantern base 28. The other section 26extends inside section 2d and abuts at one end against the bottom sideoi the llat lantern base 28. Formed in the center of the other end 30 ofthe section 26 is a small hole to receive the tubing Ztl from the pipe18. As illustrated in FIG. 2, the tubing 2i) has coils 31 formed thereinand compressed with the upper end provided with a coupling element 32adapted to be threadedly engaged by the coupling element 34 mounted inthe base 28 of the lantern l2.

In FIG. 3, the sections 24 and 26 of the coupling unit 14 are separatedalong their longitudinal axis, thereby causing the tubing 20 to expandlike a coil spring. It is noted that sufficient coils 31 of tubing Z0should be provided to avoid kinking the coil when it is extended.

In assembling the gas light lamp post it is apparent then that oneprocedure `that may be followed is to secure section 25 to the upperends of the legs 16 and the pipe member 1S; then forming a plurality ofcoils 3l at one end in a length of tubing 20, and extending the otherend through the section 26 and the pipe 18 whereupon it is connected toa gas supply.

The coupling element 32 on the coiled end of the tubing 2l) is connectedto a mating coupling element 31 mounted in the base 28 of the lanterni2, but to make this connection, the tubing 2) must be extended beyondthe upper end of section 25 to provide access to the coupling elements32 and 34. The extension of the tubing is accomplished by the coils 3lexpanding relative to each other as in a coil spring (FIG. 3). Next, thesection 24 is moved toward ysection 25 into embracing relationshiptherewith (FIG. 2) until the upper end of casing 26 abuts the lanternbase 28. The coils 3l of tubing are then in their retracted position asseen in FIG. 2. The sections Z4 and 25 are then secured against relativemovement by screws 27 being inserted thnough the walls thereof.

'With the gas supply turned on, the lantern may then be lit to provide aliame 35 (FIG. 2).

When repairs .to the lamp post are required, disassembly of the unit lliis easily accomplished by removing screws Z7 and pulling apart sections24 and 2d, thereby expanding the extendable coil 3l. Any point in theunit may then be easily reached due to the accessability afforded byextendable coil tubing 31.

Some changes may be made in the construction and arrangement of my gaslight lamp post without departing from the real spirit and purpose of myinvention, and it is my intention to cover by my claims, any modiedforms of structure or use of mechanical equivalents which may bereasonably included within their scope.
